SHEET-DELIVERY APPARATUS FOR PRINTING-MACHINES.

SPECIFICATION formingpart of Letters Patent No. 227,599, dated May 11, 1880.

Application filed February 25, 1880.

To all whom it may concern:

Be it known that I, STEPHEN D. TUcKEE, a citizen of the United States, residing in the city of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Sheet-Delivery Apparatus for Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

In said drawings, Figure l'is a plan View, Fig. 2 a side elevation, and Fig, 3 a longitudinal section elevation, of a machine embodying my improvements. Figs. 4 and 5 are, respectively, a plan, view and section elevation of a modification thereof; and Fig. 6 illustrates my improved delivery apparatus as arranged with a printing apparatus.

This invention relates to the delivery apparatus of printing-machines; and it consists, principally, in a delivery-cylinder or rotating sheet-carrier provided with'means for collecting many sheets upon its surface and of stripping the same in asingle mass therefrom, with which is combined a movable pasting device that is adapted to be adjusted in or out of working relation with said .cylinder or carrier, or automatically moved to and from such working contact, for the purpose of applying a central line of paste to one or more sheets, so that the same may be united together.

In order to apply a longitudinal line of paste to all except the last one of a number of sheets passing onto or associated together upon the surface of a collecting-cylinder, so that said sheets shall form a united pack, a pasting-disk has been fixed in working relation to such cylinder at a point forward of that at which the sheets are stripped from said carrier or cylinder.

In such relation the said disk is capable of applying paste 'to each sheet passing between it and the cylinder, but Will operate idly during that revolution of the carrier or cylinder when the collected sheets are delivered. In this relation to the cylinder or carrier it is necessary that the collecting-cylinder shall be circumferentially grooved, so that the pasting-disk, rotating in its fixed bearings, shall not revolve in contact with the cylinder or carrier, and thus apply paste to its surface when the same is not covered by a sheet, which groove some- 3 times operates to cause the sheet pressed to cling upon the cylinder, and, dampened by the paste, to buckle up to a degree injurious to perfect work.

The present invention consists in combining with such a sheet-collecting cylinder or carrier 'a pasting device that is automaticallyvibrated to bringitinto working relation to the surface of said cylinder, and there retained during the necessary periods of time requisite to apply paste to the proper sheet or sheets, or to withdraw it to a non-operative position during the passage of the sheet that is' not to be pasted, all of which is more specifically pointed out in the following description of a machine containing an embodiment of said invention.

The carrier or cylinder 20 is mounted on bearings in a suitable frame-work, and is provided with the necessary devices to adapt it to collect many sheets and deliver them bodily, as follows: A set of tapes, 11, run over pulleys or a roller, 12, thence for a considerable distance in contact with the surface of the cylinder or carrier 20, pass under pulleys or a roller, 13, and return to the pulleys or roller 12 over pulleys 14. A second set of tapes, 15,

run from pulleys or a roller, 16, for a considerable distance in contact with the surface of the cylinder or carrier 20, pass over pulleys or a roller, 17, and return under a roller or pulleys, 18. These tapes thus nearly span the entire circumference of the cylinder or carrier, but leave a space between the rollers or pulleys 12 and 17, that is spanned in part by curved guides or conductors 2, and constitutes the entrance-point for the sheets. These tapes also leave a space between the rollers or pulleys l3 and 16, that constitutes the deliverypoint for the sheets, and which is governed by vibrating switches 3. These devices convert the cylinder or carrier 20'into a gatherin g or a collecting device, as is fully set forth driven by the positive rotation of such pulleys or rollers.

The switches 3 are composed of separate pieces having curved front and upper faces, that are fast upon a rockshaft, 24, the movements of which cause said switches to rock into the grooves 5 of the cylinder or carrier 20, as in Fig. 5, or into the grooves 60f the roller 13, as in Fig. 3, according as the shaft 24 rocks them forward or rearward. These switches are so rocked or vibrated by means of a rock arm, 25, attached to the end of the shaft 24, and a connecting-rod, 26, said rod being actuated in one direction by a cam, 27, upon which its stud 9 bears, and in the other by a spring, such movements of it being governed by its bifurcated end, which embraces the shaft 28. This cam 27 is shown as proy'ided with atoothed perimeter to constitute the wheel 29, that is carried by the shaft 28 and engaged by a toothed wheel, 30, fast on one end of the shaft of the carrier but this wheel 29 and cam 27 might be separate devices.

The conductors 2 are separate curved pieces fast on a shaft, so that their faces coincide with the surface of the cylinder or carrier 20, while their rear ends extend into grooves 7 or the roller 17.

One form of the pasting device is a disk, 40, mounted on a stud, 4, that turns in a bearing carried by an arm, 41, fast upon one end of a rock-shaft, 42, that is actuated by a rock-arm, 43, aconneeting-rod, 44, and a face-cam, 45, that is fast upon the shaft 28. This rod 44 is bifurcated to straddle and be guided by the shaft 28, and carries a stud, 8, that bears upon the cam, its rearward movement being effected by a spring. (Not shown.) The pasting-disk may thus be rocked forward, as in Fig. 3, so as to be in working relation to the surface of the cylinder 20, or rearward away from the surface of said cylinder, as in Fig. 2. Its stud 4 is provided with a fast pinion, 47, that meshes with a toothed wheel, 48, carried by a rotating shaft, 50, upon the outer end of which shaft is mounted a driving-wheel, 51, that re ceives its motion from a pinion, 52, on the shaft of the roller 13. This pasting-disk runs in contact with a paste supply or fount, as in wheel 53, that is fast on the rotating shaft 50, the hubs of the journal of said wheel running in guiding contact with the inner walls of the paste-fountain 54, thatis constructed in bracket form and affixed to the end frame.

The pasting-disk is thus constantly rotated by hand from the feed-table butuit is especially designed: to be attached to a printing or other automatic sheet-supplying machine, as is shown in Figs. 4 to 6, its mechanisms bein g driven in unison with such machine by means of gears connecting with the wheels 21 29, or any other suitable one, as is set forth in the patents before referred to.

Each sheet fed to the cylinder 20 will beheld onto the surface thereof by the tapes 1] and 15, and directed by the switches 3, when they stand as in Fig. 3, and the guides 2, so as to pass onto and revolve with the cylinder.

At each complete revolution of the cylinder a new sheet will be fed to it, so that a number of sheets will be collected one upon another on the surface of the cylinder, their heads and tails being separated a suitable distance apart to admit the operation of the switches, as is now well understood in this class of machines.

As each sheet passes the point occupied by the pasting-disk it will, in passing in contact with such disk, receive a longitudinal line of paste upon its outer surface when such disk is in the working relation to the surface of the cylinder shown in Fig. 3, so that when a second sheet is collected upon this centrallypasted sheet it will adhere or be united thereto, which manipulation will be repeated as to each succeeding sheet. When, however, the sheet which is to complete the predetermined number constituting the pack to be collected is passing onto said cylinder, the cam 45 will operate to vibrate the pasting-disk into its rearward position, Fig. 2, away from the surface of the cylinder, so that it will not apply paste to this last or outer sheet. will, however, be united to the next underlying sheet by the line of paste it has received.

As the tails of the pack of pasted and collected sheets supported upon the carrier have passed the switches 3 said switches are quickly vibrated forward into the grooves 5, as in Fig.'

2, by the action of the high part of the cam 27, and thus have their points carried within the peripheral line of the cylinder 20, in which position they stand, so that the switches intercept the heads of the pack of collectedand pasted sheets and strip the same bodily from the cylinder and guide them outward, as in Fig. 2, so that they may be delivered to a piling-table before a fly, or to a folding-machine, as in Fig. 4, and as is described in Patents Nos. 197,700 and 214,067, the switches standing in that position until the pack of sheets has passed over it, and then being quicklyvibrated outward by the cam, as in Fig. 3, so as to direct the next sheets following the collected pack around with the cylinder, as is explained in said patents.

As soon as the collected pack of sheets has passed the point occupied by the pasting-disk it is vibrated forward by the cam 45, so as to bear upon and paste the next sheet passingit.

The cams 27 and 45 will, of course, be shaped and timed so as to cause the proper This sheet vibrations of the pasting-disk 40 and switches 3, according to the number of sheets desired to be collected. In the present instance this number is two, and hence these cams are correspondingly shaped-that is, the said cams, which are revolved at half the speed of the cylinder, vibrate the pasting-disk and switches at each second revolution of said cylinder, and thus cause two sheets to be collected, pasted, and delivered, but may be readily arranged to collect, paste, and deliver any predetermined number.

The pasting-disk may be adjusted so as not to apply paste to any of the sheets bydetaching the connecting-rod 44 from the arm 43, whereby said disk may be moved to and supported in a rearward position. Thus adjusted, the apparatus will collect unpasted sheets and deliver them in packs.

The pasting device may be modified, as i1- lustrated in Figs. 4 and 5, where it is shown as consisting of a blade, 33, that is attached to the rotating shaft 4, and arranged to be vibrated into and out of working relation with respect to the surface of the cylinder, so as to apply a transverse line of paste to the appropriate sheets, so that a pack of sheets thus collected and pasted will still be united together upon a central line.- In. such modification the pasting-wheel 53 will be extended as a cylinder and run in a fountain, 54, of suitable dimensions, so as to supply the edge of the pasting-blade with paste as the same in its revolution comes into surface contact with said wheel 53. The pinion 47, that rotates the shaft of the pasting device, will then be placed near the frame, as will the toothed wheel 48. In all other respects the structure is the same, and need not be again described.

In Fig. 6 this delivery apparatus is shown as attached to a printing machine and arranged to deliver' the collected sheets to a folding-machine, the cylinders 37 38 illustrating the cutting cylinders belonging to the printing-machine, and usually arranged near the same and run in unison therewith, so as to divide a printed web into proper sized sheets.

The roller 61 represents one of a pair appropriate] y rotated and adapted to nipa sheet doubled between their surfaces by a vibrating blade, as 62, and deliver s'aid sheet once folded. Such a folding-machine is of common form, and, being described in the United States Patent No. 192,034, need not be particularly explained here.

Tapes leading from small rollers, as 34 35, arranged just before the cylinders 37 38, will then be provided to conduct the sheets to the delivery apparatus, the cylinder 20 whereof will be made somewhat larger than the said cutting-cylinders, so as to accelerate the speed of the paper and separate its sheets a distance apart, as is set forth in aforesaid Patent No. 193,056.

As here arranged, the tapes 11 are extended rearward to pass over the roller 34 and forward to passover a roller, 58, an intermediate guiding-roller, 57, being provided; and the rearward portion of these tapes co-operates with a set, 64, running from the roller 35 and returning over a roller, 36, to form a conducting-channel leading to this delivery apparatus,

and the forward extended portions of the tapes 11 co-operate with a set, 65, running from a roller, 60, and returning over a roller, 59. In other respects the apparatus remains as hereinbefore explained. The sheets will thus be conducted from the cylinders 37 38,'be collected and pasted, as before described, and the united pack will be delivered against the gage 63, and be folded on its longitudinal line of pasting by the folding'blade 62.

If the pasting device is modified, as in Figs. 4 and 5, so as to paste the sheets on a central transverse line, it may be applied to a cylinder adapted to collect and fold half-sheets, as in Patent No. 197,693; or the product may be conveyed to a folding-machine, which will receive and fold full-sized sheets, as in Patent No. 171,196.

As this improved pasting device is adapted to be adjusted in a suitable relation to and be timely operated with a gathering-cylinder constructed as here shown, or as is illustrated and described in the patents referred to, it consequently operates so that the sheets collected may be pasted together upon a central line and be delivered in pairs or any other suitable number. This mode of operation greatly facilitates the production of bound work, as the signatures of books and the several sheets of a newspaper, and themechanisms, all being rotary, admit of very high speed.

Having thus described the invention, what is claimed is The combination, with a rotating carrier having means for collecting many sheets one upon another on its surface and stripping the same in a single body therefrom, of a rotatingpasting device, the shaft of which is provided with means for rocking it to move said paster into and out of working relation to said carrier, whereby the collected sheets are pasted upon lines uniting them together, all substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
